We have demonstrated a technique to fabricate carbon nano wires of controllable dimension and location using a top-down methodology. The width and thickness of the wires are in the tens of nanometer range. Additionally, the technique is capable to produce conducting carbon nano wires with addressable positioning, controllable length, high aspect ratio (length vs width) and alignment. The addressable and patternable carbon nano wires we developed can be exploited in large-scale assembly to make highly integrated nano wire sensor arrays or electronic devices.
